With dry set you really can't go wrong, because if you don't like the result, just pick em up and start over. A few tips: Do a good job setting your edges (that will hold everything together). Poured concrete edges 6" wide work best. Fill the borders with sand (between 1/2 and 2" deep-no deeper) and level the sand (this is very important). Lay each brick or block and rap the center with a block of wood and rubber mallet. Go on to the next one. Overlap the wood on adjacent bricks and rap lightly to set both to the same level. Leave a little gap between (1/4"). When you're done setting bricks, pour sand on top and sweep,sweep,sweep with a broom to fill the cracks between with sand. Hose it down with water, let dry, and keep sweeping sand until all cracks are full. Wet it down, and enjoy. In a very short period of time the bricks will set fast and will not move at all (unless you started with too deep of sand bed). That's it, and its easier done than described, just remember to start with a good solid border edge.
